The placement of T-tube drainage has an impact on the patient’s quality of life, but it is possible to take a proper bath, mostly in a special way, by clamping the drainage tube to the abdominal wall and fixing it to the abdominal wall with cling film, otherwise you can take a shower, but you must keep the T-tube orifice position dry, and the belly button can be used in a rubbing bath. Do not get the dressing wet. If the dressing is inadvertently wet during the shower, it needs to be changed in time to keep the area dry and clean, which has less impact on the patient. The probability of purulent infection at the drainage tube opening is not too great, but local protection should be paid attention to during the bathing process.
